Pack weight is 0,800 kg. Produced by manufacturer Boettger, the caps form part of the labware assortment covering containers, bottles, tins, canisters, and related consumables. Choose this variant when a PP screw cap with tube base is required for Ø 44 mm containers, ensuring a consistent seal and practical bench organisation. The design addresses routine needs for reliable closure and coordinated tube placement in professional laboratory environments handling sample storage and internal transport.

Questions about Screw caps, PP, for containers Ø 44 mm, with base for tube, 250 unit(s)
What is this article?
Screw caps, PP, for containers Ø 44 mm, with base for tube, 250 unit(s) is the article on this page. Luminix Health distributes Boettger for laboratory use. It sits in Sample containers & jars, inside Bottles & containers, in Labware.
A sample container or jar is the vessel the sample travels in, with a closure that survives the trip. The volume and the liner decide whether the sample that arrives is the sample that was taken.
A laboratory bottle is a closed container with a stated volume and a neck that takes a cap, a stopper or a dispenser. Borosilicate glass is the choice when the liquid is a solvent, or when the bottle will be heated or autoclaved. Polyethylene and polypropylene are the choice when the bottle must not shatter, or when hydrofluoric acid would attack glass. A narrow mouth pours. A wide mouth is for powders and for reaching the bottom. Laboratory ware of this kind is indexed under ISO laboratory glassware. Traceable volume sits with the BIPM and NIST Physical Measurement.
